## Topics

Energy forms
Energy conversion

## Takeaways:

Energy makes changes and movement possible in everyday life
Energy is required to enable things to work or move.
There are different forms of energy and they can be converted from one form to another.

## Description

This simulation allow students to explore the concepts of kinetic energy and potential energy. When the re-bounce case is selected, the sum of kinetic energy and potential energy drop immediately after each contact with the ground. The energy loss is typically associated with sound and heat energy loss to the surrounding by the ball.

## Sample Questions that this simulations was made to address

## Sample Learning Goals

**Recognise and give examples of the various forms of energy. - kinetic energy - potential energy
**Investigate energy conversion from one form to another and communicate findings.
